Excellon 129 Vision Drill Machine allows precise alignment of drill to image ensuring complete IPC Class 3 compliance on even the tightest tolerance high layer count boards. Also, with its 180K spindles, its capable of drilling high quality .006” and .008” holes and precision depth controlled via stub removal or mechanical blind vias. Typical fabricators cannot drill .010 or .008” holes optimally because they have 110k spindles which are not capable of reaching optimum drill surface feet per minute. This results in rough hole walls which can cause stress points and via barrel cracks resulting in early field failures.

Excellon Cobra Dual CO2/UV laser machinging center allows blind micro vias as small as .003” and tight tolerance flex machining to image +/- .002”. Typical fabricators contract this process and have no control over the quality.

Horizontal Direct Metallization with spray impingement and ultrasonic’s prevents air entrapment in high aspect ratio small vias allowing for quality copper plating even in the center of micro vias. Typical fabricators rely on mechanical agitation while processing panels vertically. This does not effectively remove air bubbles causing small voids in metallization which cause thin plating which can result in field failure opens.

Patented High Aspect Ratio acid copper plating system using titanium anodes and knife edge agitation allows 1:1 surface copper plating to hole wall. This provides for increase reliability as the copper ductility inside the hole is greater than with typical systems, and thus reduces the likelihood of field failures.

Microcraft Electrical Test latest generation capable of testing wirebond pads as small as .003” pads. Also has special fixturing system for reliable testing of thin core flex circuits.
